If you get sleepy in the middle of hot days, you are not alone. You are not even alone in the animal kingdom.

Biology may be behind it.

We know that many people have a harder time sleeping in the summer and be slow to get out of bed on colder mornings and new study hopes to connect sensory neurons and neurons that control this cycle.

The work is only in fruit flies, so it goes in the exploratory pile despite the hyper-coverage such studies get in corporate media, but they found that fruit flies are pre-programmed to take a nap in the middle of the day. They believe there is a brain thermometer only active in hot temperatures.

There is concern about US states making their own abortion laws in the US, but in Germany most abortion is illegal. It is only allowed for medical or criminal reasons within 12 weeks of conception, and lack of body autonomy may be why most Germans are fine with mandatory COVID-19 vaccines.

The molecular mechanism that drives the disease-causing effects of the most common genetic risk factor for lupus,  HLA-DRB1*03:01, has been revealed in a new study.

Systemic lupus erythematosus is a common, incurable autoimmune disease that affects millions of individuals worldwide, with a particularly high prevalence among women. The genetic variant HLA-DRB1*03:01 is the greatest risk factor for the condition, which involves inflammation in many vital organs, and can lead to severe disability and death.

In the study, investigators found that a protein coded by that HLA variant triggers a cascade of molecular and cellular effects that can cause the inflammatory symptoms seen in lupus patients.

Hot on the heels of COVID-19, Monkeypox is in the news for an alarming spread among people who engage in risky sexual behavior, because it is transmitted primarily through direct contact with infectious sores, scabs, or body fluids.

Healthcare professionals, particularly those in general practice, gastroenterology, and colorectal surgery, are going to need to discuss sexual behavior to make patients better informed. A new analysis of survey results finds that applies to young heterosexual women as well.

The Multicentre Epilepsy Lesion Detection project (MELD) used over 1,000 patient MRI scans from 22 global epilepsy centers to develop an algorithm which provides reports of where abnormalities are in cases of drug-resistant focal cortical dysplasia (FCD) – a leading cause of epilepsy.

Around 1 percent of the world’s population have the serious neurological condition epilepsy, that is characterized by frequent seizures. While drugs treatments are available for the majority of people with epilepsy, 20 to 30 percent do not respond to medications.

An experiment found that selfing” monkeyflower plants lost 13 percent to 24 percent of their genetic variation compared to another group that were propagated by bumble bees. 

Genetic variation is important to respond to changes in nature or the overall environment. The good news is that they used bumblebees and though they claim they are in decline, evidence does not show that, so the plants are not at short term risk. Even better, pollination is not done by bumblebees alone, there are over 25,000 species of just bees, and lots of other insects pollinate. An experiment outside a closed greenhouse would show that.
